Forms

combustibil m (plural combustibili)[1] Adjective: combustibil m or n (feminine singular combustibilă, masculine plural combustibili, feminine and neuter plural combustibile).[1] The first record, in J. Cihac (1837), has the French form combustible.[2]

Etymology

It is borrowed from French combustible (“combustible; fuel”).[2][3][4][5][1] DELR explains the French word as formed on combustion with the suffix replaced;[2][1] Wiktionary takes it from Middle French, from combust, the past participle of comburir, and -ible.[2][1] Behind it lies Latin combūrō (“to burn up”), formed con- and ūrō (“to burn”), with the ⟨b⟩ taken from ambūrō (“to burn around”).[2][6]

Earliest recorded meaning

DELR and Tiktin date the first record to 1837;[2] DELR's quotation, from J. Cihac, still has the French form combustible.[2][4] Negulici's dictionary of 1848 gives both the adjective, “having the property of burning, of combining with oxygen”, and the noun, anything that feeds a fire.[7]

Semantic evolution

Romanian took over a whole family of these French terms in the same years: combustie “combustion”, combustibilitate and incombustibil appear in Negulici's dictionary of 1848, comburant in 1852, and necombustibil, formed in Romanian on the model of French incombustible, in 1870.[2]

As a noun the word came to mean the fuel used for heating and as a source of energy in industry.[3][8] Technical phrases followed: combustibil convențional, a standard fuel of 7,000 kcal/kg used to compare real fuels, and combustibil nuclear, fissile material burned in reactors.[3][9] DELR dates biocombustibil “biofuel” to 1964.[2]
